摘要
Some copper and bronze wares unearthed from the bronze coffin tomb at Dabona Cemetery, Xiangyun County, Yunnan Province have been identified by metallographic method. The results showed that they were made of copper, tin bronze and lead tin bronze with very low tin proportion, the alloy ratios of which reflected an immature development stage. The microscopic structures of these metal wares showed that the techniques applied to them were diversified, including after-casting thermal processing and cold processing. The diversified manufacturing techniques implied the multiple sources of Dabona Bronze Culture. The 14C dating results of the wooden outer coffin unearthed from Dabona Cemetery showed that the date of this bronze coffin tomb was the early to the mid Warring-States Period.
